Although it has been known since the time of Newton, nearly three centuries ago, that bodies attract each other according to the law of inverse-squares, no explanation as to how gravitation operates has been accepted. However with our present knowledge of matter it would seem that some explanation should be possible. Keeping in mind Newton's first law of motion, namely, "Everybody continues in its state of rest or of uniform motion in a straight line unless compelled to alter that state by impressed force", let us consider for the purpose of illustration an atom within the motion is that produced by the electron as it rotates on its own axis, or as it travels in an orbit around the nucleus, or by the vibration or the rotation of the nucleus in part or whole.
